I really want to get a hold of the indent areole and belly-button scop. I think mine is the exposed areole clone, but who knows till it grows more. I got it too late in the season this summer for it to grow much and now it's dormant. And on trout's site he shows several seed grown specimen that are spineless! Where did they get the seeds?? I want them. I've only found scop hybrids. I actually have some scop hybrids going and they all have spines. Even when scop was the mother.
Another trait I look for in genuine scopulicola is the baseball bat/club shape. Skinny at the bottom and getting fatter towards the top.
I think I have a prejudice for spined ones since I searched for so long for a spineless specimen. It really was a lot of trouble trying to find one. Until I asked SS for a scopulicola. I didn't ask for a spineless one, but the one they sent me barely had spines. The ironic part is it told my friend immediately that they had spineless ones knowing that he wanted one. He bought one from them and they sent him one with visible spines, which he already had.
